Embodiment 1
[0022] (1) Tea picking: before and after Qingming, pick healthy and straight yellow tea buds without insect damage, or one leaf and one bud first unfolded, one bud with two leaves, one bud with three leaves;
[0023] (2) Withering: The tea leaves are subjected to vacuum anaerobic treatment, the vacuum degree is 0.02MPa, the vacuum anaerobic temperature is 22°C, and the time is 3 hours; then the tea leaves are spread indoors, the leaf thickness is 7cm, and the temperature is controlled at 25°C. The air humidity is controlled at 60%, withering naturally for 60 minutes, turning the leaves every 10 minutes, so that the grassy smell of tea leaves disappears;
[0024] (3) Classification: use a classifier to classify the withered tea leaves into 1-3 grades according to one leaf and one bud, one bud with two leaves and one bud with three leaves;
[0025] (4) Finishing: Put them into the green fixing machine in sequence from the first level to the third level for 7 minutes, and the tem...

[0032] (1) Tea picking: before and after Qingming, pick healthy and straight yellow tea buds without insect damage, or one leaf and one bud first unfolded, one bud with two leaves, one bud with three leaves;
[0033] (2) Withering: The tea leaves are subjected to vacuum anaerobic treatment, the vacuum degree is 0.05MPa, the vacuum anaerobic temperature is 20°C, and the time is 5 hours; then the tea leaves are spread indoors, the leaf thickness is 10cm, and the temperature is controlled at 20°C. The air humidity is controlled at 50%, withering naturally for 40 minutes, turning the leaves every 15 minutes, so that the grassy smell of tea leaves disappears;
[0034] (3) Classification: use a classifier to classify the withered tea leaves into 1-3 grades according to one leaf and one bud, one bud with two leaves and one bud with three leaves;
[0035] (4) Finishing: put them into the green fixing machine in order from the first level to the third level for five minutes, and the te...
Embodiment 3
[0042] (1) Tea picking: before and after Qingming, pick healthy and straight yellow tea buds without insect damage, or one leaf and one bud first unfolded, one bud with two leaves, one bud with three leaves;
[0043] (2) Withering: The tea leaves are subjected to vacuum anaerobic treatment, the vacuum degree is 0.03MPa, the vacuum anaerobic temperature is 21°C, and the time is 4 hours; then the tea leaves are spread indoors, the leaf thickness is 8cm, and the temperature is controlled at 22°C. The air humidity is controlled at 55%, and the leaves are naturally withered for 50 minutes, and the leaves are turned every 12 minutes;
[0044] (3) Classification: use a classifier to classify the withered tea leaves into 1-3 grades according to one leaf and one bud, one bud with two leaves and one bud with three leaves;
[0045] (4) Finishing: put them into the green fixing machine in sequence from the first level to the third level for 6 minutes, and the temperature of the fixing mac...
